One of the results of the fabled and oft studied Miami Shootout of 1986, where two FBI Agents lost their lives when attempting to take down two violent felons, was the conclusion that the 9mm round used by agents at the time failed to adequately perform its job to incapacitate its target. As a result, the .40 caliber round rose from the aftermath and eventually worked its way into law enforcement agencies across the nation, with the notion that it had the “capacity of a 9mm, and the stopping power of a 45.” But this alleged increase in terminal performance did not come for free. Over the years, the louder report and snappier recoil made it hard for many trainees and officers alike to have difficulty qualifying, the ammunition costs more (than 9mm), and there is increased wear on the pistol (as well as the hands and elbows of the shooter.)
